1) THE SE ROM SLIDESHOW
In the ROM of the original Macintosh SE (*not* the SE/30!) is a four-frame slideshow composed of
digitized b&w images of the development team.
To view the slideshow, hit the interrupt switch to enter the debugger, and type the following:
G 41D89A .
Alternatively, you can write a program which calls this procedure:
PROCEDURE DoIt;
Inline $4EF9, $0041, $D89A; { jmp $41D89A }
The slideshow is an endless loop; once started, the only way to quit is by rebooting (or turning the
power off).

This icon exists at different locations |
